Letters- Patent No. 110,4'82, dated December 27, 1870.

IMPROVEMENT IN vWASHING-MACHINES.

The Schedule referred toY in Ehese Letters Patent and making part of thesame.

To all whomit may concern:

v 1 Be it known that I, MOSES S. MARSHALL, 'of Somer= ville, in thecounty of Middlesex and State of Massachusetts, have invented certainImprovements in Washing-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference beingv had to the accompanyingdrawing and letters of reference marked thereon making a part of thisspeeitication', 'in which- Figure 1 is a side elevation of my invention;

Figure 2, atransverse vertical central section and Figures 3, 4, and 5,views of` parts in detail. v

This invention relates to-that class of washing-machines which arecylindrical in shape, and revolve on hoiizontalbearings, otherwiseknown' as rotary Inachilies 5` and .V

.It consists mainly in an improved method of ventilatiug `the cylinder,and in an improved method of attaching the cover or lid; also in certainminor details ot' construction for keeping the cylinder right side up,or in any desired position when not in operationas will hereinafter morefully appear.

In the-drawingv A represents the cylindrical machine, which isconstructed of corrugated sheet-metal, the corrugations a operating likeordinary wash-boards.

The cylinder A is provided with journals B B, which have suitablebearings in the frame O.

' D D represent tubes leading from lthe interior of cylinder'A. into thecircular case E, which surrounds journal B, but does not partake of itsmotion.

The ease E is provided with the tube F, which leads from the-bottom ofthe same downward, and also with the bent flange e, which incluses aprojection on the end of cylinder A. l

H represents a convex perforated partition like the rose of awatering-pot, which covers 'the' inner ends oftubes D, and prevents thesame from being stopped by the fabrics within cylinder A.

I represents an oval or other-shaped orifice in the cylinder A, which oritice is surrounded by the upwardly-projecting flanges J K, whichlatter have a space between themselves. v

L represents a cap or lid corresponding in .shape to Oriiiee I, andprovided with the downwardly-projecting flange l, whichienters the spacevbetween anges J K, and is rendered water-tight by means of packing.

`NN represent projections on the sides of lid L. between which arespaces, n n, into which enter the pivted screw-bolts O, which areprovided with nuts P, which latter, when screwed down, firmly secure thelidL. A

' The object of the orilice TI is to insert'the fabrics and water forwashing. v R represents a weighted space in cylinder A, opposite thelid, which weight keeps thelatter upperlnost v when not in operation. l

Sis anednctiou-pipe beside weight R.

T T represent sockets on the end of cylinder A, into whichenters the endof pin U, which passes through frame C, and therebyholds the cylinder Ain any ilesired position. V

Vrepresents a Acrank attached to journal W W represent horizontalshelves o'n the inside of cylinder A, which operate to detain thefabrics in' the same, and causing them to -drop with more or less force,thereby facilitating the washing operation.

c It will be readily seen that by the arrangement for ventilating, thesteam or spray which escapes is caught and collected in case. E, fromwhence it passes olf through tube F into-asnitable receptacle,

I am aware that rotary washing-machines have been l circular casejE,havingtube F, substantially as `described. v

2. The lid L, having flarge l and projections N, in combination withcylinder A, having llanges J K and pivoted bolts O, substantially asdescribed. 3. The weight R, in combination with cylinder A,substantially as described.

In testimony whereof I have signed my name to th' speciticetionin thepresence of two subscribing -MOSES S. MARSHALL. Witnesses:

' CARROLL D. WRIGHT, CHARLES F. BROWN.
